The majority of modern motorcycles are covered by two types of annual service schedule, a minor cheaper service, and a further reaching major service. The major service normally includes the replacement of spark plugs and air filters. These two types of service tend to alternate every year, providing a balanced cost of ownership. It’s a common misconception that annual services are just an oil & filter change and a wipe over of the bike! While this may be tongue-in-cheek banter, it couldn’t be further from the truth.  STV have access to Larsson’s servicing database and every minor and major service covers all of the checks and adjustments the manufacture specifies based on the mileage of the motorbike.
